TIRE BOOT AND FASTENEB THEREFOR.

Application led'November 20, 1926. 'Serial No. 149,7(19.

. so construct the boot that the connecting element may be readilyattached thereto and the inner tube is protected against wear ordestruction by engagement with said connecting element.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is an insideelevation of a tire boot constructed in accordance with my in- Vention;

Figure 2 is a transverse sectional view on the line 2-2 of Figure 1;

Figure 3 is an enlarged fragmentary side elevation showing the sectionsof the connector separated;

Figure 4 is a plan of the blank from' 'with the female section of theconnector is formed;

Figure 5 is a similar view of the blank forming the male section of theconnector.

Referring now more particularly to the drawings, the numeral 10generally designates a tire boot, the body portion 11 of which isrelatively thick at the central portions of its side edges. From thiscentral portion, the boot is tapered to a line or feather edge at theends thereof. To the inner face of the body adjacent one longitudinaledge thereofl is secured one edge of a flap 13 of suiiicient length tobridge the gap between adjacent edges when the boot is in v the closedor normal position.

A fastener for connecting the edges of the bootto one another isprovided and comprises male and female sections 14 and 15.

The male section 14 comprises a relatively fiat body having projectingfrom one side thereof a series of spaced stems 16, each provided at itsouter end with a transversely extending head 17. The body portion isprovided with means 18 whereby it may be secured to the longitudinaledge of the boot.

In the preferred construction of the male element 14, a metallic blankis folded intermediate its end edges and from the edge produced by thefold, portions of metal are removed to produce-necks 16 and heads 17.From each of the strips thus produced and upon adjacent faces of thesestrips, tangs are struck-out to form the securing means 18, these tangsbeing staggered with relation to one another. f

In the initial construction, the tang bearing strips 19 are left indivergentrelation to one another, so that sufficient space is providedbetween the adjacent faces to enable the insertion of the relativelythick portion Vof the longitudinal edge of the tire boot therebetween--These st-rips 19 are then forced together, so thatthe tangs 18 enter thematerial of they boot and firmly secure the element 14 thereto.

The female element 15 likewise comprises a strip of metal foldedintermediate' its end edges. With this element, the portions 20 lying atopposite sides of the fold are left in spaced relation to one another.One of the elements is provided with a series of slots 21 correspondingto the head portions of the male member and through which the headportions of the male member may be inserted to the space between thesections 20. These slots have branch slots 22 for the accommodation ofthe neck portion '16, these branch slots extending through the bight 23connecting the sections 2O and into the other of the sections 20, sothat the neck portions may have a limited oscillatory motion when theheads 17 are in position between the sections 20. rJhe slots 21 arespaced from the folded edge or bight 23, so that the' heads 17 must bemoved transversely of the section 15 before they will properly alignwith the slots 21 for removal therethrough. As at this time the bightedge. 23 will be engaged against the edges of the sections 19, it willbe obvious that this removal will be accomplished with the male andfemale members in parallel relation, thus preventing accidentaldisengagement of the sections in event one end of the fastener isvcramped in any manner. The body portions 20 are provided with tangs 18asimilar in construction and arrangement to the tanfrs of the sections 19to permit attachment of this section of the fastener to the opposit-elongitudinal edge of the boot.

It will be obvious that when the fastener is in applied position, thenatural strain applied by the tube will tend to separate the sections ofthe fastener and thus hold them more rmly in engagement with oneanother. The flap 13 interposes between the tube and the fastener andthus prevents any abrasion of the tube Which might result in injurythereto.

Since the construction hereinbefore set forth is capable of a certainrange of change and modification Without materially departing from thespirit of the invention, I do not limit myself to such specificstructure except as hereinafter claimed.

I claim l. A fastener' for use with tire boots and the like comprisingcoacting male and female sections, each consisting of a folded plate,the male section at the folded edge thereof being notched to provideoutstanding necks having heads at their outer ends, the female sectionof the fastener' being provided in one side thereof adjacent the foldededge thereof with slots through which said heads may pass and branchslots for the passage of said necks connecting with the first namedslots of the female section and extending from the first named slots toand through the folded edge of the plate.

2. A fastener for use with tire boots and the like comprising coactingmale and female sections, each consisting` of a folded plate, the malesection at the folded edge thereof being notched to provide outstandingnecks having heads at their outer ends, the female section of thefastener being provided in one side thereof adjacent the folded edgethereof with slots through which said heads may pass and branch slotsfor the passage of said necks connecting with the first named slots ofthe female section and extending from the first named slots to andthrough the folded edge of the plate, the free edges of said platesbeing provided upon the adjacent facesthereof With tangs for engagementin the edges of members to be connected.

In testimony whereof I hereunto aniX my signature.

CLARENCE L. JOHNSON.
